Best motocross game

This app is the best motocross game of app store but now, you should add some tracks... How about st-louis, daytona,etc. The computers are extremely slow, even on hard, 7 laps, I finish first with one lap on the second... Multiplayer is good but we sometime hit and fall but no one has hitten they other one. There are still some ameliorations to do but time trial is awesome! And thats why I give 4 out of 5
